Baden-Baden-Aquae, Capital of the civitas Aurelia Aquensis

See this text in


Foundation and structure

The settlement began with the construction of a fort, shortly after the right bank of the Rhine's was conquered, c. 75 AD. At what date the town became civitas capital, is unclear, although the honorific ‘Aurelia’ might suggest a foundation by Marcus Aurelius (emperor 161-180 AD). The town's size and importance were heavily dependent on the exploitation of thermal springs, and inscriptions demonstrate that the spa which developed around them was frequented by soldiers from various units, including the legion stationed in Argentorate-Strasbourg.


Germanic settlement

Pottery finds suggest the presence of a Germanic settlement in the first half of the 1st century AD.


The military installation

The fort lay on the Rettig hill, south of the thermal district and the ground plans of barracks have been traced during excavations. Occupation began around 75 AD and may have ended before 84 AD, which is the date given by a building inscription from what might be a later building.

The town and its structure

The Rettig and thermal district are the best known parts of the ancient town. The distribution of finds suggests a settlement at least 600m long, but the Roman town is not well enough understood to allow any statement concerning its overall plan, or the design of its street grid.

Public buildings and infrastructure

The hot spring area was occupied by several large thermae, which were closely linked to the site's role as a spa. The partially excavated Imperial Baths (Kaiserthermen) have so far yielded four large pools (at least 53m x 18m) and a hypocausted room. Its construction dates to the early 2nd century and an inscription recording a restoration dates to 213. Only a series of hypocausted rooms is known from the Military Baths (Soldatenbäder), but a further large bath complex is attested by a large building (K) between the other two.

Part of a building excavated on the Florentiner Berg, in the immediate vicinity of the Kaiserthermen, has been interpreted as part of a Gallo-Roman temple acting as a sanctuary to the spring source. Parts of the area's rocky surface had to be levelled during its construction and a concentration of stone dedications suggests the presence of another sanctuary, near the modern Friedrichsbad.

Roman remains at the Florentinerberg

After the abandonment of the fort, the Rettig area was used by a sequence of stone buildings, which were probably of a public or administrative nature. This is particularly likely in the case of the incompletely known Bau I (width c.28m). This has an apse and its construction has been linked to an inscription dated to 84 AD.

Stone structures on the Rettig hill

A building inscription mentions the guild house of the carpenters (schola fabrum tignariorum).


Residential buildings

The town's residential structures remain largely unknown, although an area containing several rooms, one of which seems to have contained a food shop, has been excavated in the Gernsbacher Strasse.
